The class 98 10 locomotives (unofficially GtL 4/5) were superheated steam locomotives of the Deutsche Reichsbahn .
After the vehicles of the Bavarian type GtL 4/4 had proven to be very reliable and all had been taken over by the Reichsbahn, it was decided to replicate them. However, since they were quite slow at 40 km / h, the construction was modified and the so-called GtL 4/5 was created with an additional rear running axle , which was connected to the last coupling axle to form a Krauss-Helmholtz steering frame .
Krauss initially delivered five copies of these machines in 1929. Six and ten more locomotives followed in 1930 and 1931. The remaining machines were manufactured by the newly established Krauss-Maffei company in 1932 and 1933.
Despite the additional running axle, the maximum speed could only be increased to 45 km / h, so that later on further modifications and new constructions based on the GtL 4/4 followed ( series 98 11 (1'D) and LAG No. 87 and 88 (1'D1 ')).
All 45 class 98 10 locomotives remained with the Deutsche Bundesbahn after the Second World War . Retirement began in 1957 and was completed in 1966.
